Hi I'm not a very techy person and I have a few questions that I hope you folk can help me with... First, as a Mac user I of course can't use PC Studio, and there is - strangely - no mention at all of it in the instructions that came with the phone. So does the program enable you to do anything crucial? I notice that when I plug the phone into my Mac, it doesn't appear as an external drive. So is a program is needed to make them talk? Also, I know people have posted here about an unofficial way of updating the firmware, but I'd rather do it the official way, given that I don't understand what I'm doing! But what is the official way? Will I receive an update automatically over the mobile network whenever there is an update? The current version is I7500XXIH6. Finally, the reason why I'm interested in updating the firmware is to see if it removes a couple of problems I'm having: - the screen frequently locks at random times, well within the timeout setting, and often while I'm actually using the phone (I'm definitely not even touching the lock button) - when the screen is locked and black, it randomly comes on for around a second, before going black again, even when it's just lying on my desk Thanks in advance for any help you can provide!
