If you don't have cash to burn then simply keep watching for now. The firmware update will either make or break this phone. You will have issues with it if you are coming from the iPhone. The user experience is sub-standard if you decide to comapre. Also, tmobile 3G/3.5G kicks major *** when compared to ATT. They might also be subsidizing the phone in the future.

This basically reminds me of the N95. It was great when it came out but the problems started showing really fast. What did Nokia do? The N958GB which basically kicked ***. Just wait for the update.
