Good Evening aviator,
Good Question! There isn't an application that I'm aware of however, maybe one of our community can help on this one?
There is a command that you can type into your phone which displays when you last updated on the network (for both GSM and GPRS). All you need to do is type *#105# and then send. Hope this is of use!
Let me know if there is anything else at all!
