They're a little late to the party
, but it looks like Alltel has started slipping its own variant of RIM's BlackBerry 8830 World Edition into retail channels in the past few days. Thanks to a 900 / 1800MHz GSM radio packed in there beside the standard CDMA / EV-DO fare, the 8830 gives subscribers to CDMA carriers like Alltel a somewhat painless route to international roaming without juggling multiple handsets. The cameraless posterior means that the 8830's pretty much all business -- but with GPS in the mix, it's a darned good business to be in, we reckon. Check it for $250 on contract after rebates.
