Remove 10 minute restriction?

I've read that it should be possible to bypass the IP Check somehow to remove that damn 10 minutes restriction that usually doesn't let me do something I actually logged in for. Any ideas?

All it's does it prevent you from getting items from the mail and selling/buying things from marketplace, go do a dungeon run, by the time you're finished 10 minutes will be over...lol

I don`t think there is a way to bypass it, unless you just login with the same IP obviously..
I think they save your last logged IP at their servers, and when a new IP logs in to that account and doesn`t match the one at their server, you get the 10 minutes error.
So you can`t bypass it. (Obviously you can hack their servers but it`ll much more than 10 minutes and its illeagel :P )
