i have samsung y duos, android 2.3.6. (after rooting according to your description it still shows this version.)
my problem: i have extreemly low upload speed. download about 1-3 mbt (enough for me), and upload not more than 95 kbt. when using voip they don't hear my voice. is the problem with phone model or android version? help please.
when using another way of sim card connection network is ok
