I'm running 4.2.1 with the ultrasn0w unlock on a 3g, used redsn0w .9 6 b5, and i only recently noticed that while i do get a bit more crashing than i did before (ie. multitasking is a gamble sometimes; if i try to access a safari link from within an email it will crash the phone without fail), i only recently noticed a fairly serious (for me) problem: If i try to add a repo under cydia's 'sources', the first time i press 'add' nothing happens, and it acts like it brought up the add box except for the fact that it didnt. If i press add again, Cydia will freeze, and i will have to close it out.

It does this every time i try- does anyone know whats going on or where a better place to ask this question would be?
