Right.. After my friend tried to ring me.. I sat my phone with FULL signal next to me & tried to call it from my landline. Nothing. Phone unavailable! So called Vodafone & it seems my 2G signal hadn't updated since yest afternoon. So I had to go settings, carrier & choose manual search, selected any network other than Vodafone, then wait for no service to appear, then go back & put Vodafone back on. Voila. 2G updated. BUT since then, I've been calling *#105# frequently and it's just NOT updating automatically. 3G is, not 2G. Why should I have to reset my network every cpl hours?!! I'm really angry now. I'm taking screenshots of everytime I do the time check call & it's very clear 2G is NOT updating. W H Y???
