I tried using OpEdit to overwrite my alpha text but it didn't work. I'm running the latest unbranded version for t-mo zn5's, is it not possible on this version?
Only way to hide this that i know of is to edit the homescreen_p.ini file of the skin that is applied.
The drawback is that you have to sacrifice the time as well.
Open the homescreen_p.ini file with wordpad and look to the section for [Font_DigitalClockStd]
Change the line that reads "size = ??"
If you set to 1000 that should do the trick.
Save the changes and reload to the phone.
