Since I’ve been able to compare my SIM unlocked iPhone to Dan’s virgin iPhone, I’ve noticed a few remarkable differences!
- the menu animation on my iPhone is noticably sluggish
- the screen brightness on my iPhone is dimmer than Dan’s
- my iPod and Safari crash a lot
A lot of other people have also reported that after a SIM unlock, the speaker volume drops as well.
What on earth?
It’s certainly looking like ye olde SIM unlock isn’t as pristine as we once thought!
The screen brightness drop isn’t something I have any idea about, but the chunky animation seemed like something fun to try and nut out.
After many wasted restore attempts and other efforts, I started to wonder if the lacking performance has anything to do with the absurdly long and equally ugly ‘YES OPTUS’ gracing the top of my screen.
Turns out that it did…
It seemed to make sense – unlike AT&T, or O2, iPhone is reading the Optus logo from the network each time it loads, rather than from a PNG image on the phone. Additionally, the software is then forced to scroll the carrier name because it doesn’t fit the gap (which occasionally caused some bizarre stretching and the like).
So at least in my mind, it looked like I’d found a possible way of getting performance back to how mother Jobs had first intended it to be, while satisfying my anal retentive tendencies.
Dan came across a great tutorial on how to rename the Optus carrier logo on the iPhone, which we set to work on pronto!
As iPhone does read from the network, it’s not as simple as swapping an image file over… Though you do get to put your own image in there once you’ve used a Hex editor to re-jig the springboard.
The result? After loads and loads of testing, I am confident to say that I think I have at least finally gotten rid of the sluggish animation! It is like a brand new iPhone once more!
Some people have still reported sluggishness even after a restore, however it is not stated whether they were using it on AT&T (image logo) or another network without an image.
So I’m happy. My saga of shitty animation looks to have come to an end.
Mind you, I should point out that I don’t have App Tapp installed on my iPhone, only custom number formats, You Tube and the SIM unlock. I think Dan went through a similar process without quite as much love, but he’s fully pimping it with the 3rd party apps, so that is perhaps a bit of a trade-off.
For what it’s worth, Safari hasn’t crashed on me as much either. Placebo?
I’m not sure if I could say the screen’s any brighter, however! I guess I’ll save that for another day!
