3GS upgrade to OS 4.2.1, no service with 3GS turned on
Hi,
yesterday i upgraded my iphone 3GS to OS 4.2.1. Fortunately, unlike previous upgrades, everything went smoothly and after about half an hour the phone was running the new OS.
However, today i noticed i had no signal - just "No Service" at the top-left.
After a quick look on google i found someone mentioning having 3G turned on affected them, so i tried turning 3G off.
Sure enough, after a minute or so my signal came back and i have a full 5 bars on Vodafone UK. However, whenever i go and turn on 3G the signal drops to 1 bar for a few seconds before then going to "No Service".
Also, the phone does feel slightly warmer to the touch than it should.
Is this a general problem for other 3GS users in the UK, or am i unique?
Is there anything i can do, other than trying to revert to an earlier version? I really dont want to do that as i've had updates brick the phone before and i dont want to have to go through recovery mode again 😟
