Hi,
I recently purchased a J10i2 Elm upon noticing that it supports GSM850, upon receiving it I noticed it does not support UMTS/HSPA 850 (umts 5). There is basically no info on these phones yet, so is it possible to patch it to support umts 5 (850 MHz)? If I go into the service menu it states it supports umts 1 and umts 8 my old K850i does not have this info in there so it is almost like it is locked by software to those frequencies.
I can only assume there are other Sony phones like this?
