The BlackBerry Curve 8520 seems to be headed to T-Mobile soon. There is still no date leaked for this device, but we would estimate sometime later this year. The BlackBerry Curve 8520 is an 2G phone, lacking the 3G bands needed. We are still in awe as to why RIM is still producing 3G-less devices, but that is for another post. The Curve 8520 has a optical trackpad and will have Wi-Fi/UMA.
