My bad experience with blackberry. I don’t want to use this again in future:
Battery back up sucks
After some time, keypad gives up, you have to put extra pressure to get things moving (there are issues but still workable)
Not much free software available for the device as it is available for I phone, so adding new software to your black berry curve, just forget about it.
4.Display screen is quite small, so reading full length documents is a tedious task.
Cant send sms through laptop after connecting via bluetooth which you can do with nokia symbian based phones
Making wifi connection is easy but you dont get much speed in wifi on phone, quite sluggish speed
Not fully functional desktop or pc interface software
