Instead of using GPRS to do my updates and downloads I use my Broadband Internet connection via ethernet with my computer with the connectivity settings to pass through instead of Smart GPRS... haha kuripot ko talaga.
Hence it should work even with the Globe GPRS Internet connection as long as you get Internet connectivity.
It's kinda fun browsing with the Tanager for free, but after a while, why will you browse the web when you have a PC in front of you.
But this is very useful for Action Backup and Update. I've tried Backing up and restoring, after a hard reset, using their service. Besides losing some very minor settings like profiles and locale.. everything went smoothly..
