strange things about op logo

some time ago, when i downloaded the blank op logo, i discovered that the blank logo would work only for some time, and then it would go away, and my provider's logo would replace it. i had to either turn my phone off and then on again, or do *3370# so that the phone would do a restart. that would bring my blank logo back up (for a while, however)

now, i dont have to do that anymore. one day, about 6 months after buying my current phone, i woke up and the blank logo was still working, the next day the same, the next day same thing, etc. my blank logo stays in my phone forever now, it does not come back unless i turn it off myself. i dont have to turn the phone off and on anymore because the blank logo is working now how it is supposed to work.

do any of you know why this happend? did it just decide "oh well, im going to let him have is precious logo... he keeps me clean and safe anyway!"

Lol. That's a bit strange. Once I upload an operator logo, it stays like that.
