iconios
I had this app called Spark for working environment communication.
However, the status bar icon of this app is so ugly that I avoid look at it every time when I glimpsing over status bar.
The worst thing is there is no option for hide it in the settings. Is there anyway that I can forcefully remove it?
Its the TTY icon, according to this Apple KB. You can go to Settings -> Phone to turn it off.
TTY, Teletype (or various other names for it) is a special device you can use on a phone to help those that are deaf or hard of hearing communicate. Not sure why it would be enabled with the new SIM, unless there was something on the account on the new SIM that enabled this, and Apple did something to read this setting and configure their own setting.
You can safely turn it off if you are not using one of these machines.
It looks like the application is adding that icon. I checked the Level application on my phone (sort of a free demo for Carpenter) and it has a button with the same design in the upper right corner:
Tapping the button gives this screen:
Google still has some update notes cached where the developer listed this as a new feature in the App Store:
Added Quick Switch button on the top right corner to quickly switch between iHandy apps without getting back to home screen.
Normally, apps can't add custom icons to the status bar. According to this thread, they may just be overlaying the Quick Switch icon over the battery indicator: Customizing iPhone app taskbar

Try Bartender. This lets you hide (as well as re-arrange) menu bar items, as well as providing a secondary menu bar so that you can hide icons from the main bar but still have access to them on a keyboard shortcut or menu bar item.
