Hi, Odd request here but I use Sugar Sync, Dropbox and Google Drive for my file storage needs and when I tether off my restricted iPhone data plan - I need to quit the programs every time and then restart them when I get back to a regular wifi. I was curious if anyone knew of a software that would block specific app's from transferring when connected to specific wifi's? I had emailed Sugar Sync and Drop Box but got no replies back from them, figured that would be a good option to have in their software where if you set the wifi "John's iPhone" it would not sync as that was a wifi that was very restricted on Bandwidth but would automatically resume once back to a normal wifi like "John's Home". Anyone have any thoughts or advice on how they handle such things when they are tethering? Its a big issue for me as I am a web developer and work with Adobe Files which can be very large and every save = a upload and that is not a good option for a Mobile Data Plan on AT&T. Thanks!
