Decision is certainly yours but many satisfied BlackBerry users look somewhat scornfully at the Iphone.....however, many BB users also own Iphones and love them. Others, like me, are more interested in the pragmatic aspects of the cell phone and the few advantages that the Iphone does posess are relatively insignificant to me. If possible, find a friend or anyone willing to let you play with the Iphone for some time. Also, keep in mind, ATT has a 30 day policy whereby you can return the phone......perhaps that is your best option. Personally, I think of the Iphone as more of a toy and the BB as a tool......you will soon tire of a toy but tools seem to last a lifetime......good luck on your choice.
