First off, Android 2.1 is a flop. It doesn''t allow you to run apps from your SD memory card. Avoid it entirely unless you wish to use this as a basic phone only and you can get it really cheap! Probably should be ~$15 less than a Flipside with Android 2.2 from what I have seen. Android 2.2 is much better for running apps and is the oldest version of Android I will entertain- and only version in the Flipside I will entertain. But what hamstrings this phone is its memory management and awful lack of internal memory, even in 2.2. A good SD card itself is not enough to make it run well. If you are a budding Android hacker you will see there are some workarounds. I''ve done some of the less intrusive ones which has helped a bit. But to get rid of the awful ATT bloatware from the internal memory in order to get anything resembling stability & functionality you have to "root" your phone. Google will help you find this info- but be warned that it MIGHT destroy the phone and it WILL void your warranty. And it will take time & effort. I believe I will be trying this when I find time. Once these particular hindrances are thrown off I fully expect this phone to be all I wish. (If you expect the latest & greatest just go get the latest & greatest- it cannot be found for under $70!) If you want to avoid the hassles this phone brings- and most should probably avoid it- there are other low end Motorola Android phones available for not that much more cost. See the Motorola website, and do your homework looking at reviews. Still- I like my Flipside; it has above average signal in fringe areas which is a must for me. I like the keyboard. Its performance is just fine when it is not wigging out from its paltry internal memory being overloaded. If you enjoy challenges, you might really like this phone. If you have zero desire to download apps or do much streaming media, you may love this phone. Otherwise, understand its limitations and strengths then decide if it might be worth an extra $30 to $50 to upgrade a little. In any case, doing your research is advised.
