While we here @ thecellfreak are all Twitter fans, it seems like not everyone is pleased with the mini blogging platform: T-Mobile is allegedly blocking Twitter access for some of their customers.

According to Mashable.com, A T-Mobile customer service representative responded via email finally to one of the customers complaining, which was posted later to BibleBoy Blog:

“Twitter is not an authorized third-party service provider, and therefore you are not able to utilize service from this provide any longer.”

”T-Mobile would like to bring to your attention that the Terms and Conditions of service, to which you agreed at activation, indicate “… some Services are not available on third-party networks or while roaming. We may impose credit, usage, or other limits to Service, cancel or suspend Service, or block certain types of calls, messages, or sessions (such as international, 900, or 976 calls) at our discretion.” Therefore, T-Mobile is not in violation of any agreement by not providing service to Twitter. T-Mobile regrets any inconvenience, however please note that if you remain under contract and choose to cancel service, you will be responsible for the $200 early termination fee that would be assessed to the account at cancellation.”

Besides of this being a weird act on behalf of T-mobile, it's also a great opportunity for Twitter to prove they actually take their mobile users seriously. Once Twitter is going to fight back, then we'll know for sure that they are all pro-TXT twittering and not just claiming to be mobile friendly. So yes, this whole thing can be a test of sorts -- proving the importance of mobile 2.0 usage.
