I stumbled over an interesting free email service for your mobile phone that uses the email clients already installed on your cellphone.
Momail lets you setup several email accounts online and all emails arrive on your mobile phone in a single inbox. I tested the service on my Nokia N80. During sign-up you can choose your phone model and Momail sends you an SMS with the automatic configuration. This makes the setup quick and easy.
Receiving and sending then works directly from the messaging interface of the Nokia N80.
Momail also uses compression for email attachments to reduce the amount of bandwidth.
Momail just informed me that the service also works with the Apple iPhone, only the configuration is still manual. See the configuration below for the momail on iPhone service.
Momail is for end consumers who do not use push email services from RIM or Microsoft, but still want their email on their mobile phones.
Momail is a Swedish startup founded in 2005. The service went into beta in 2006 and has been available on a broad basis since Spring 2007.
You can sign-up and find out more about Momail on their site.
