wildfire hell


hi all
ok problum i have
i love the wildfire great phone
i bought my wildfire off ebay 1 mouth old so got it a little cheapper than the new price .
it was locked to 3 network
i had it unlocked for any sim and was going to debrand it as well but found out the 2.2 version cant yet be rooted :(

so the problum i have now is iv put a payasyougo o2 sim in i can text and make calls but no aceess to the internet or mms .
o2 sent all the setting and iv checked all forums and checked the settings .
iv read many forums and have seen prople with the same fault with the o2 sim and i tried a orange sim and the same problum . i could put a 3pay sim in but the signal where i live is pants

question : does anyone know the way around this or is it because 3pay have branded it and sown it up ?
