I plan on traveling internationally this, which means I will be using an extremely small data plan (think 20mb/month) in order to save money. I primarily want to use this plan to check my email (I am hoping 20mb will be enough for email). I am wondering if there is a way to limit data access to certain programs, like the email client. That way I could be sure that no other programs or system updates are eating through my data. I also plan on pre-downloading maps to use with the GPS, so I want to make sure those programs don't use data either.
