Just like Solutor said - itīs a shame, that none of the brand mobile manufacturers is able to make a serious dual sim phone with two radios.
For about 3 years i'm using Samusng B5702 and i'm satisfied. But...I need a new toy
Unfortunately, none of the phones with touch screen is capable to replace it. The only one, which could, is ZTE U960.
3 years and only 1 phone comparable. Veeeery sad.
