reMail Search [AppStore, Free]

reMail Search is a new application available for free in AppStore (link). It allows users to perform accurate searches in emails. There is an automatic completion of keywords in the search mode, so you can find neccesary emails very quickly.

reMail Search also works offline. The application, in fact, downloads e-mails keeping them in the cache on your iPhone / iPod Touch. reMail Search also works with all IMAP accounts, such as Gmail. The application is compatible with iPhone and iPod Touch, requires upgrading to firmware 2.2 and is localized in English.
