A company called 24/7 Mobile Solutions announced a product called SIMable today. SIMable is a very thin chip that you attach to a standard SIM card. When the two chips are inserted into a locked mobile phone, SIMable makes the phone behave as if it were unlocked, meaning it can be used on different networks. SIMable does not alter the phone's software, nor does it void manufacturer warranties. Phones will be returned to their locked state as soon as the card is removed. Any phone unlocked with the SIMable product will retain all its working functions, including access to 3G networks.
