Hi, Recently I've started facing a problem on my Desire. Sometimes it acts like the network is down, and the signal bar shows a cross. At that time when I tried another sim card, the network was working fine. Then after a while my phone starts showing network with the original sim. But it won't connect to the internet. It simply won't connect, although I am toggling the mobile data connection tick mark. Right now the network has gone again, and I'm trying to get connected to it through either Automatic registration or manually selecting from the list of network providers. But I get the message "unable to connect to this network at this time"... Please help me guys... Could it be a problem with my hardware because it's an on and off problem? I bought the phone from a different country from where I'm living right now, so it would be difficult to get warranty service. What do I do?
