A review of the RIM BlackBerry Pearl Flip 8220 handset has been posted over at MobileBurn.com. 'The RIM BlackBerry Pearl Flip 8220 for T-Mobile is rated for 4 hours of talk time or up to 14 days of standby time. While the standby time seems optimistic, at least when used with T-Mobile's UMA(INFO) based WiFi VoIP service, the talk time seems pretty much on the money. Reception from the built-in antenna is about average, but the call audio is pretty good overall on regular calls. The speakerphone performed decently, but was nothing to write home about. The Pearl Flip 8220 lacks any 3G support at all, but works on all 4 of the major GSM/EDGE network bands used throughout the world. And thanks to that UMA support, the phone can be used on any available WiFi network for clear VoIP calls without worrying about any possible GSM reception issues.'
