Ok, so I have a blackberry 8900 unlocked and on pay as you go, which means I cant use instant messengers because I dont have the blackberry data plan, but I do have data plan. Also I have an iPod touch 2nd Gen 16 gb. But I was thinking on getting the iPhone 3gS unlocked and sell my touch and 8900, so my question is this: would you rather have the iPhone 3gS or the iPod touch and the blackberry 8900? Which is better if youre on pay as you go? If I get the iPhone will I be able to use instant messengers and use the app store? I want it to be unlocked.
