Why another Twitter client?
With the rise of Twitter users and the increase in the adoption of Windows Mobile devices around the world, the need for a client that allows those Windows Mobile users to utilize as many of the features of Twitter as possible without needing to be at a desktop computer increased as well. And as the rates for mobile Internet access and the surcharges incurred by mobile providers for SMS messages increased, the need for a full-featured, yet simple-to-use, client presented itself as a need. Thus, Twobile was born! And even though Twitter provides a web-based interface for mobile devices, its functionality was not as robust as those found on the desktop-version of the web interface.

How much does Twobile cost?
Absolutely nothing. Zip. Nada. Zero. Why, you might ask? Because Twitter is free and the ways you access it should be too! We do, however, ask that you donate to us so that we can maintain the Infinitum Software website and the Twobile software if you use the software for personal purposes. If, however, you use it for marketing, promotional, or other business ends, you will be required to pay for the software if you intend to keep it and begin using it for those business-related ends. We believe that this is a reasonable request to those who love the software as it will help us build a better program and better support for it.

Does Twobile work through a third-party server? Is my information secure?
Twobile directly connects to Twitter and all transactions are performed between your Windows Mobile device and the Twitter service. We do not syphon any information like direct messages, statuses, or username and passwords from you. There is no interference between Twobile and Twitter that we artificially inject that would be cause for alarm. However, upon your first successful login and use of Twobile, will will ask you if you would like to add the Twitter user "Twobile" to your friends list. This is optional and absolutely not required, but it will help us convey information about new updates that are available for Twobile when they are released, information about what is coming up, as well as any other notices that we may decide to make public. It also allows us to figure out how many people are using the Twobile client and where in the world they are using it (if you have set a location in your Twitter account). This, though optional, is just for bragging rights, and we hope that you can help us be proud of our little tool.

Pre-Installation Requirements
Although Twobile is nearly self-contained, there are some minimum requirements for its usage. Please review the list below prior to attempting to install Twobile on your Windows Mobile device:
- Windows Mobile 5 or above.
- Touch-screen device (Windows Mobile 5 Pocket PC or Windows Mobile 6 Professional Editions).
- At least 2MB of memory.
- At least 1MB of storage for installation.
- Internet connection.
- Microsoft's .NET Compact Framework Version 2 (Requires a Windows PC to install.

Installation
Installation of Twobile is very simple. Prior to installation, download and install Microsoft's .NET Compact Framework Version 2 for your device if you do not have this installed already. If you already have this installed, you can skip this step and continue. If you are unsure, it is recommended to try to install it anyway, but if your device already says you have it installed, it is recommended NOT to reinstall it unless you are having problems.

Next, download the CAB file for Twobile to your device. On your device, use the File Explorer program (Start > Programs > File Explorer) and navigate to the location where you placed the CAB file for Twobile. Open the CAB file and the installation will begin. If you have a memory card installed on your device, you can choose to install the program either to the storage card or into main memory. It is recommended to install it to your main memory for program stability, but if you do not have enough space on your device, you can choose to install it to your storage card.

Once the installation has been completed, you can click OK to exit the installer and start Twobile by clicking on "Twobile" in your Start menu.

Important note for existing 1.0.x users upgrading to Twobile 1.5.x or 1.6.x:
Please uninstall Twobile 1.0 Beta completely before. To do so, go to Start > Settings > Remove Programs and remove Twobile 1.0. Also, using the File Explorer or other file management software, navigate to the Program Files folder on your device and delete the Twoblie folder to ensure that all settings and cached files are removed. After this has been done, use the download link to download and open the install file (or if you've already downloaded it, open the CAB file).

Update Description:
v1.6.8 (29-01-2009):
Bug Fixes:
- Temporarily fixes issues with logging in. Some devices using cellular connections with proxies may have issues. This issue is caused by a recent change with diagnostic tools provided by Twitter and will hopefully be resolved as soon as possible.

v1.6.7 (03-10-2008):
Bug Fixes:
- Discovered and fixed bug caused by .NET Compact Framework not sending authentication header despite being told to during request sequence. This fixes problems with some people who have private Twitter profiles and are unable to log in through Twobile.

v1.6.6 (30-09-2008):
Bug Fixes:
- Added menu item to from About screen to Diagnostics dialog.
- Fixed issues aggregating the Friends list from Twitter caused by a recent unannounced change to the Twitter API.

v1.6.5 (29-08-2008):
Features:
- Added new integrated automatic self-diagnostics system. By launching Twobile in a special way, some connection issues can be diagnosed by running a series of tests to determine where the problem lies. To launch the diagnostic system: Quit Twobile if it is running, then press-and-hold the action/center button on your device while tap-and-holding the clock, then select "Run" and in the prompt type ":TWOBILE" without the quotes (be sure to include the colon and capitalize the word TWOBILE), and press OK. Documentation on how to determine what the errors mean, if any occur, will be posted at a later date.
- Added the ability to open a Google Map on the device displaying a user's location if the user has posted GPS coordinates from within the Profile View window. The ability to zoom in and out has also been added.

Bug Fixes:
- Temporarily fixed startup routines, so that when Twobile is run at the startup of your device, the Twobile main screen is hidden.
- Fixed some HTML character codes from appearing when translating text.
- Fixed some functionality in the Twitter connection libraries to try accessing resources at least twice before failing and reporting errors to the user - this attempts to solve some issues with Twobile in which the application appears to not even try to use an Internet connection and issues errors (actually, Windows Mobile causes this error).
- Twitter connection libraries also now accomodate for the fact that users may be using a proxy server (i.e. if you are on AT&T or T-Mobile, for instance). Twobile attempts to connect without a proxy server, but if the request fails during an automatic diagnostic test, then Twobile switches automatically to using the system's proxy server (the proxy server used in Pocket Internet Explorer).

v1.6.4 (12-08-2008):
Bug Fixes:
- Fixed the "Retweet" feature to include the name of the original poster.
- Fixed the profile images functionality so that when viewing the originating tweet of an @Reply, the profile image is not downloaded (saving bandwidth and memory).
- Added ability to "retweet" from within the Message View.
