Johannesburg, May 31 (ANI): White House hopeful Mitt Romney has meticulously spelled out his vision for a better America while on the campaign trail this year with his new mobile application.

The With Mitt application for the iPhone allows users to express support for the recently anointed Republican flag-bearer by personalising a photo with an overlaid Romney slogan.

Trouble is, one of the slogans has a howler of a spelling mistake - A Better Amercia.

Members of the proofreading public recently made the discovery and it went viral on Twitter late on Tuesday, with people mockingly tweeting photos showing the Amercia message.

Some poor app designer is getting strapped in a cage on the top of a car and driven across country tonight. #amercia, News24 quoted one user as tweetijng in a reference to Romney's hard-to-live-down decision years ago to strap the family dog in its carrier on the roof of the car during a vacation.

On Wednesday, the app, promoted by official campaign website, had yet to be corrected, and new downloads contained the spelling error.

Mistakes happen, Romney's campaign spokesperson Andrea Saul said on MSNBC.

I don't think any voter cares about a typo at the end of the day, she added.

The spokesperson added that an update had been sent to Apple and was awaiting final approval. (ANI)
