question about personalizer 2.0 and 3.1

[mwrood]

i was wondering if anyone knew whether or not either of these use memory or additional power consumption...the reason i ask is because ive always used 2.0 and in the description for 3.1 it says that everytime your phone wakes up the screen flashes and the carrier name is rest to what i altered it to...so again, does anyone know whether these use momery/battery power...and if so, does one use less than the other...thanks in advance
