Anyway you can change the locking system or set the wallpaper?

The unlocking button is in a very awkward location and I heard somewhere you can set it so it's like the iphone where you just slide it?
I hate how it cycles through the lame default pictures on the lock screen. What causes it to switch and is there any way to set it to just one, or preferably my own picture? My friend saw the sunflower on my phone and asked if I was gay.

If you find the button difficult to deal with (depending on what kind of protector you have, if any) you can always just slide the keyboard partway out and it'll come out of the locked screen.

Unfortunately, we have been unable to solve the dreaded locked wallpapers fiasco...

There's a handy search feature at the top. 

And yes, there is an easy way to disable the internet capable features of your phone without affecting texting and/or MMS messages.

He is telling you to search using the search box at the top of the forum. What is useless about that? In any case here is what you were looking for.

I suggest you at least take some time to look at the stickies of the forum.

It doesn't make it useless, it just shows that we have lots of useful info and people with questions should check first before asking a question that has already been answered multiple times.  Welcome to the forums, helping yourself to the information already available is the first step to becoming an intelligent Impression user. 

The charging port is also the audio port but you need the adapter cable that will allow you to connect a standard minijack headphone cord into it.  You can get one on ebay for about $0.99 usually.

As for the games, without internet you have to use our special install method.  USE THE SEARCH BOX to answer your question.  If you would take the time to read the sticky posts in each sub-forum you would answer your own questions well before having to ask them.

New problem, the bottom left of my screen (vertical) squeaks a bit when I press on it. I just got this phone and the ATT store doesn't have anymore impressions. Anyway I can fix this myself?
