Hello. I have 700 minutes plus Unlimited internet and messaging on my ATT account. All this costs about $130-$140 with tax. TM offers unlimited everything I listed above for $79 plus tax. TM does not carry the Iphone yet, but I have an locked IPhone 3Gs, which I plan to use with TM. So, here are few questions: I will obviously have to unlock my IPhone 3Gs in order to use it with T-Mobile. How do I proceed with unlocking my Iphone? Any best solution recommended? If I switch to TM, will I be able to access all of the mac specific features such as seamless Itunes integration with backups of my Iphone? What I about all of the Apps that are on my Iphone now? Will they work and will I be able to update them through Itunes? Will I be able to access the Apple APP STORE to buy new apps? What will be different (besides the cost) if I switch from ATT to TM? I guess that the new ICloud will be only available through ATT, or not? What feature(s) will I loose and miss? Any other comments coming from those who have switched to TM??? Thanks in advance.
