Showing Talk Time Usage

[hamidxa]

I purchased a couple of phones, one used (Sprint Touch Pro 2), one "New" (an imported Touch HD).

Surprisingly enough, the Touch Pro 2 (which was on Mighty ROM when purchased), shows usage time of 0 hr. 0 min. 0 sec. both for incoming and outgoing calls, despite the fact that the previous owner admitted it was used for about 3 weeks (for about an hour a day).


The Touch HD on the other hand is running Dutty's ROM, and shows usage time of 34 hr for incoming and 32 hr. for outgoing, despite the fact that the previous owner stated it was new.

My question then becomes, how is it possible that the geniunely used TP2 with Mighty ROM shows 0 hrs 0 min 0 sec for incoming and outgoing talk time, and how come the allegedly "new" Touch HD shows 34 hrs and 32 hrs for talk time.

Where is that information even stored, how is it retrieved, and why does one clearly not store it, whereas the other seemingly does?
