So, the wife and I were given a pair of optimus F3's (and new T-Mobile service, to boot) for christmas. My wife, being the app fiend she is, filled up her internal storage within 30 minutes. Naturally, she came to me crying about how "this phone sucks, I can't load my games, you said this phone is 10x better than what I had", etc. I checked, and sure enough, she was using these games that are downloading huge amounts of additional app data. I attempt to mitigate this by ordering her a 16GB sd card, only to find out the phone is treating the internal storage as the primary SD, which games are targeting......you can probably tell where this is going and are already prepping links. I've looked, and I think that this is quite the promising solution, but my wife adamantly does NOT want to root. The question is, since I can't root and I already know where the games are going (/SDcard0/Android/), and since I have write permissions there already, can I not just symlink to /external_SD/Android/ and be done with it? Second, I'm a little out of practice with the linux mklink command, so what would be the exact level of the directory structure to create the symlink and have it be permanent/transparent enough for games to be fooled? I've rooted mine, on the other hand. Since my primary gaming is done via emulators, I just put all my roms on my own 16gb card and avoided the whole problem in the first place.
