Cannot help with the issue that I am having with iPad here. Really cannot help it. I have not jailbreaked but still I get the issue with this iPad. I have to travel a lot so I have two SIM cards and I use them depending on the availability of the Signal Strength that I get. Now I was using the other SIM (The one from Vodafone) as I was not able to find the connections with the Regular SIM (H3G SIM) there. When I was getting back I have seen that it is not allowing me to use iPad with the H3G SIM. Really weird and it has happen for the first time after I upgraded iPad with iOS 4.2.1. Any suggestions.
