Hi, I have a Samsung GTI5700 (Galaxy Spica), that was on virgin, and I recently unlocked it so I could use my orange contract sim in it. After unlocking though, I can no longer use certain features such as the mobile internet, and downloading content from multimedia messages. I can however still connect to wi-fi access points and make and receive phone calls and texts just fine. I have mobile internet browsing as part of my contract so it must be a problem with the phone, and must be caused by the unlock, since I could use it fine with the old pay as you go virgin sim. Is anybody familiar with this problem or phone, or has any suggestions as to what could be wrong and how I can fix it?
