Motorola Charm :: Wireless And Network State Not Working?

after purchasing a charm with motoblur last week, i was able to set up my motoblur account through wi-fi, send and receive messages as tests to make sure the phone was working through providers at&t and t-mobile (because i had unlocked and inserted an existing british simcard on the network "3"). i opted to not enter the browser/marketplace due to the price of roaming abroad.after travelling back to the uk today, i was able to make a couple of calls and around twenty sms's with no problems whatsoever, but as i was not roaming abroad any more, i tried the browser, marketplace, maps and Internet. none of these worked due to the network state being disconnected, despite being connected to the provider "3" (found going through settings>status>network connection state: disconnected). thus when returning home, i hunted around the internet on the computer to find a way for browsing to return, just in case i'd by accident declined something earlier in the week. i came upon the "master reset / factory data reset" page on the website: https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/49373/~/charm---master-reset-%2f-factory-data-reset

after following these instructions, the phone reset. ok. then, when going back through the welcome/getting started intro to the phone, there was still a failure of network connection, and any wi-fi connections with the correct password entered always ended in "wrong password entered," or it ignored the previous password and a vicious circle of correct password after correct password began.
