I don't know about it displaying the wifi connection but there is a way to change what it says in the notification bar. It was mentioned somewhere in the slepnir thread at some point maybe try asking airtine? Hope I helped!

 

I used "Build Prop Editor" to have mine display my name as the carrier!!

 

Build Prop Eitor app..scroll to "RO cmda" & change what it displays and save/re-boot

 

Thanks! That worked great. I had tried a view carrier change apps and none worked. I have edited my build prop for 3g enhancement before and followed your advice to change the carrier = success!

Now I have successfully debranded my VM phone. No more VM boot animation and changed carrier to Sprint. lol. I also put a small carbon fiber sticker over the boost logo on my elite. The reason I did this was people making fun that I had a Virgin Mobile phone. Now they can't tell.

 

The carrier name is static and coded in the framework (eri.xml I believe) what you're wanting to do is have your current Wi-Fi connection show up as a notification? Meaning you want it to show whatever connection your currently on?

 

The carrier's name, as it is displayed in About Phone in System Settings, and on the Notifications panel, can be altered in build.prop. For example, for a time in Sleipnir's earlier RCs in place of the carrier it would say "Sleipnir." Changing what carrier network you are on is a different, and a legal gray area, story. However, concerning the current wifi network, and whether or not that may be displayed in place of your carrier name - basically anything in Android is possible.

If you're not having any luck with us here on Phandroid, try XDA-Developers or a Google search to see if its been done before. If it has, most likely it's done through an init.d script, which Sleipnir has kernel-level support for if you're running it. Not sure of other ROMs off of the top of my head (it's 2:34am, can't sleep), but init.d was something I finally finished kernel-level support for with regard to Sleipnir.
