Right now I am running Mystery's older one V1.4 with
FuzeBerry Manilla V6 with black background (looks and works great) added on by me.
Mystery's has lots of stuff but not too much and is really stable. I've tried most of the ones in the upgrade section, they are all good, and made my own too.
Don't be shy, it's really easy to flash or reflash to stock, most everything in upgrades is stable enough and reliable enough...even for a work phone.
My last phone was a touch too, and finally with the diamond Everything works like it was supposed to, the phone part is great if you ask me compared to 67006800and6900, finally the phonepad enters the numbers and sounds as fast as I dial them, not the case with all of the old phones I listed, talk about lagging, it's like heaven now
