Just to correct some misconceptions:

1. The 7-11 logo CAN be changed: https://www.speakoutwireless.ca/speak/?forum=4&topic=41&page=1

"Oxygen" doesn't list my 1112.
No 1600 either. Just 1650
2610 is there.
6061 is there also too.

I guess it all depends on which phone MattC has.

1. The 7-11 logo CAN be changed

Whether you do it directly or via some third-party software you're still messing with the phone's firmware. Make a mistake and your phone becomes a useless brick.

2. The logo represents only the vendor who sold the phone, NOT the network.

That's what I said. It's part of the "branding" process. It has nothing to do with the SIM in the phone.

2. The logo represents only the vendor who sold the phone, NOT the network. It appears no matter what SIM card is inside the phone, AND before the phone is connected to any network.

As for the word SpeakOut that's onscreen the rest of the time, all you can do is turn off the phone, remove the battery and Sim card, and insert a different company's Sim card. Here in Canada, you get to choose between Speakout, PetroCan, Rogers or Fido.

I was under the impression that some of the features on my Nokia 6061 were somehow disabled.

That is quite possible. GSM phones can be "branded." That means that the phone can be customized by the carrier who sells it. That's probably how the 7-11/SpeakOut logo got on the phones sold by 7-11. Usually branding also cripples certain functions that the carrier either doesn't support or doesn't want you to use. If your 6061 came from Rogers then it's probably customized to Rogers.

For example, I have an unbranded Motorola KRZR K1. I have both the manual for this version as well as the manual that comes with the Rogers branded K1. The menu map for the Rogers phone has an additional top menu called "Rogers Mall" with submenus that would allow me to buy ringtones, download movies, etc. from Rogers. There are quite a few other differences in the rest of the menu maps even though both phones are the same make and model. I presume the customization is done with different versions of firmware.

In addition to branding, the carrier's SIM also can customize the phones menus, or at least certain submenus, to offer carrier-specific features.

in the US and other parts of the world it is somewhat important to know what network you're on... Find a friend who has a phone on Rogers or Fido, and slide their SIM card into your phone. You'll probably see that "Speakout" has been replaced with "Rogers"

Correct. I have two European SIMs. When I insert either into my phone I get "Rogers" network displayed where it otherwise says "SpeakOut." This is to inform me who I'm roaming on. Also I'll often get an SMS from Rogers welcoming me to Canada and to their network.

In the US and overseas, when there is more than one GSM carrier you can set your phone to use a specific carrier or to automatically use the one with highest signal strength.

My guess (and it's just a guess from past observations) is that the "SpeakOut" label is there to tell you what network you're on. Up here in Canada that info is next to useless, but in the US and other parts of the world it is somewhat important to know what network you're on.

I'm using my SpeakOut SIM on an old Rogers phone (that's still locked to Rogers) and it has had "Speakout" on the screen from the moment I slipped the card in.

Find a friend who has a phone on Rogers or Fido, and slide their SIM card into your phone. You'll probably see that "Speakout" has been replaced with "Rogers".

What do you want it to read? Rogers? It's impossible to remove.

Does anyone know how to remove the 'SpeakOut' text on the phone ?

Thanks
