Hi everyone, I m blackberry user planning to switch to iPhone 4 (NOT iPhone 4S) , I understand that I can update my iPhone 4 OS to iOS5. Please tell me that would I able to use iChat on iPhone 4. I only want it for text chat (NOT FaceTime or something like that - I am not familiar with that). I believe iChat is just like Black berry messenger. Please do reply me in this regards, Waiting for your reply so that i can choose iPhone4 accordingly. Thanks Maverick.
