i got a choice to buy a BB pearl. the 8100 is an old version of pearl, i dont think i'm going to buy it. my dilemma is at the 8120 or 8110. the 8120 has wi-fi, and the 8110 has GPS. i don't know which one could be more useful. i'm in the middle school and i like candybar phones. good job BB you're the best.
