The folks at Reg Hardware managed to get their mitts on a BlackBerry 8820 and aren’t overtly impressed with the Wi-Fi capability. The UMA format of voice handover works fine, depending on your network, but doesn’t jibe with many VoIP clients, let alone how the lack of SIP support gets in the way of corporate PBX phone systems. The reviewer also had some issues getting Google Talk running and BlackBerry Maps while on the Wi-Fi. On top of that, e-mails wouldn’t send if the radio receiver was off. It sounds like if both Wi-Fi and cellular connections are on, things should work hunky-dory, but that’s quite the strain on your battery. Besides Wi-Fi, the BlackBerry 8820 is supposedly packing the microSDHC support which we love so very, very much. Hopefully the shortcomings of Wi-Fi will be ironed out before widespread sales start. It seems that in the haze of voice handoff hype, we forgot that there’s a lot of other things, like e-mail, that we’d like to hand off to Wi-Fi as well.
