technically, I saw that my curve can get 21 days
hehehe. gotta love RIMs exaggeration and the reason why they got 21. Optimum signal strength, no profiles, not touching the screen, no led indicators and no emails coming in, basically, a paperweight
for hefty price I paid for my Curve, I think I'll actually use it
I think if you can get 1 day of HEAVY usage, you should be lucky. Iphone 3g battery needs to constantly be charged (throughout 24 hours).
