Is there any way to remove or increase the limit on the number of characters displayed for the app title under the icon? I like to rename some apps and some of the names I choose go over the limit. Any help would be appreciated.

Unfortunately unless you jailbreak there is no way to change or edit them.

It is jailbroken, and I already edit them, I just want to increase the number of characters a title can be before it cuts them off. For example, I want to rename iTeleport to Remote Access....but when I do it comes out like Remote...ccess because it is too long.
