I'm on T-Mobile with the T-Zones data plan but no BIS/BES, 8900 with OS upgraded to .206. My problem: every once in a while when connected through WiFi, the web browser (both "hotspot" and "T-Mobile") stops loading pages, except those located at blackberry.com. When this happens, the BB can still ping all web sites, so the wireless router connection and DNS service work just fine (and so do apps like TwitterBerry). The browser, however, is stuck in this state until I toggle WiFi off/on. Does anyone else have this browser problem and is there a solution?
