Erica’s at it again with a cool app for customizing your carrier name text on the go. She’s created “Make it mine” which let’s you change the text on the iPhone itself without having to hack any files. This is great for people like me that was annoyed with the “Rogers Wireless” carrier name that animates for a second when you turn on the phone (or wake from sleep) and then it reverts to “Roge…” on the iPhone. Yeah, it’s a minor annoyance but one nonetheless which has now been addressed with Erica’s app. The nice thing compared to other hacking methods, is that you can easily revert to the default carrier name for those times when you are roaming and want to know who you’re paying the ransom to.
UPDATE (August 2010): Make it Mine is still available from Cydia and works fine with iOS 4 and the iPhone 4. I’ve also found that usually, after performing a firmware update (effectively undoing a jailbreak), the carrier name change you make still sticks. You’ll have to re-jailbreak to change it again but it survives the upgrade.
