Just downloaded PRL 3029, I still get a 1X icon on my Huawei M835 (which is a 1X/EVDO phone). In fact, I have yet to see 3G anywhere in the Boston area, not even in Boston itself.
When roaming on Sprint in CT (1900 PCS band), the phone reliably rebooted once an hour. But after applying the recent software update (B666) to the phone, it still reboots down there but it did not do it as often.
