mdram- No, I knew I had 2Gb of main memory before and I still have that now. I also checked with root explorer and those apps are all still ONLY referenced in the SD card folders, no reference at all in the main memory. Most of my larger apps I installed are on my SD card, like TD Ameritrade stock manager, Audible.com, CNBC, Netflix, Sling, several games, pandora, Flight tracker, Phone Voice recorder, Sirius XM Radio, Jazz Radio, Call Announcer, Forum Runner, QR Code.
Satelliteguys app is installed on SD card but while it loads, does not display any thread content. This bug has been present since the last update I did back in November during the warning bug. I complained about it and reinstalled several times but the app still doesn't work right. I wish Scott would kick them in the ass and fix the app. Note- I have problems with it on my ipad too but there it just has dead spots on the screen. Anyway, not about this thread topic.
I installed Sprite Backup and this has to be in main memory and still there and works fine. I also have Adobe Reader in main memory.
