I see you posted this a couple months ago. Did you end up finding something?

This is a phone for a 10 year old.
Androids and such have their uses, but I'd really rather not have one in this case.
Battery life is poor, they are expensive to replace, and for panic-mode emergency dialing they're too clumsy.

So if I could get an informed recommendation, I would be very, very grateful.

Requirements:

• Must be useable with a prepaid service, service area in northeast Ohio
• Must have a standard dialpad (flip phone/clamshell, slide-down, bar, etc)
• Must have GPS
• Must be able to run a GPS tracking program (don't care about navigation) like Google Latitude, Accutracking, Mologogo, etc.
• No full-face touch screens

Bonus:

• Under $50
• Slide-out keyboard
• Camera

The Samsung Entro and Samsung M575 from Virgin look good, but I'm not sure if they'll run a GPS location app (or if there's one available).
The Samsung Array & Samsung Factor from Boost also look good, but apparently Boost blocks 3rd-party access to the GPS in their CDMA non-smartphones. I know Sprint also sells the Array (for $$$). Not sure if the Sprint firmware could be flashed over the Boost firmware to make the GPS available (or if the Sprint firmware is even available).
I'm willing to pay a few bucks a month for the GPS locator software if necessary.

Thanks in advance!
