After Sprint, AT&T hops on the Centro smartphone bandwagon. The phone is now available for $99.99 on AT&T’s EDGE network. The price tag comes after a mail-in rebate and a two year service contract.

Centro allows the user to make calls (of course), send text messages and IM messages, check his email and browse the web. Not bad for a lightweight device like Centro. Maybe this turns out to be another best-seller for Palm (and will hopefully help the company revive).
