As if easier typing in landscape mode wasn't enough, the Mail.app enhancement known as TouchType has now implemented better spell checking for your emails.
Sure, the iPhone corrects typing as you go, but this is the first time "aggregate" spell checking has been offered. Explains TouchType creator Mike Schneider:
‚ÄúI am really proud of the spell check feature. The results are very
accurate and it works in 86 languages. I was planning to make spell
check its own application, but when TouchType was unexpectedly approved
by Apple two weeks ago, I decided to merge the two programs. The
updated TouchType is still $0.99 and is a free update for existing
The newest version of TouchTYpe offers support for all international characters
and symbols, save functionality (enabling users to reuse text in email
messages and create multiple email signatures), and general increased
stability and bug fixes.
