I just bought a new phone with a 30-day trial with Sprint and I'm having mixed feelings now. I got the Palm Centro. It is a very nice phone but there is one big problem with it. The battery drains so quickly that I seemed to be constantly charging it. I don't even use the web that often and the battery still drains fast.
Does anyone else have a recommendation? I may look at the 3 phones below as a possible switch over if I don't like the Palm Centro.
BLACKBERRY
The Blackberry Pearl looks nice and slim but I heard the Suretype keyboard takes time to get used to. The Blackberry Curve also looks good but a little bigger than the Pearl. Does anyone use one of these and what is your opinion of it? Is it true that you cannot transfer Contact info from another phone into the BB? That would be a big drawback if that is the case since I have alot of contacts on the phone. Below are some cons about the BB.

Cons:
No picture messaging
Can't separate your call log
Cannot transfer contact info into phone from other phones
Some complaints about the trackball
Pros:
Thin and small
Better speakerphone (from what I heard)
PALM
I saw the Palm Treo 755p and it looked rather bulky.

Cons:
Bulky looking
Pros:
Lockbox accessible
Picture messaging
Can separate your call log
Can transfer phone contact into the phone
Have you bought a new battery and tried that? I had a battery that drained quite quickly on my Trio, I bought a new one and, viola, the charge lasted well over two days!
