My brother has been admiring my iPhone and would like one himself but is not keen on the O2 iphone tariffs. Who could blame him for that. I would be very interested to hear from anyone who has managed to unlock their U.K. 1.1.2 iPhone and is using it successfully with an O2 non-iPhone sim card such as Simplicity 15 which gives 200 minutes and 400 texts per month for £15 and has the option of a data bolt-on (200Mb fair usage limit) for an additional £7.50 per month. This £22.50 per month arrangement would suit him down to the ground. If you are in this or a similar position I would be grateful if you could post your experiences here. Does everything except visual voicemail work, e.g. EDGE (when available), Email, YouTube, Safari, SMS etc? Have you noticed any downsides such as reliabilty issues? What method did you use to jailbreak? I'm aware of the tutorial at http://hackint0sh.org/forum/showthread.php?t=15849 but it all seems very involved and suitable only for computer nerds. What about http://www.iphoneunlockuk.com/ ? I appreciate that it costs money but if it works and can be achieved without the hassle, it may be worth it. I'd appreciate your comments.
