Rogers Wifi C905 WTF NEED HELP

hello to all, im brand new on this forum and also new to debranding unlocking, etc, however i have an extensive past in computer stuff.

in any case, i recently recieved a new c905 from sony ericson (due to warrenty stuff, long story, but the k850i have a design flaw which sony still denies but decided to give me a free phone anyway) in any case, the c905 has wifi but cannot go on it for some weird reason. it finds networks, lets me connect to them successfully but the browser wont browse to any page!

Ive unlocked the phone via unlock code, ive also debranded (is debranding the same as flashing?) the phone, which also worked with generic north america cust pack or whatever. and still i cannot surf on wifi.

any ideas on what i should do next would be appreciated. thanks.
