Review: Helio Fin
The Fin is the second phone to use Helio's new unified inbox. This is a one stop shop for text, MMS, email and IM. It is set up as a list with a separate entry for every type of protocol. Each item in the list is two lines, one to tell you which it is, and another to tell you how many new and read messages are waiting for you. The text on this list is in a smaller font than nearly anywhere else on the phone so that you can see most of the list without scrolling.
To centralize things a bit, you can choose to be alerted to incoming messages in a unified alert window, which shows a summary of the messages and allows you to read or delete them. In addition to text and MMS, the inbox supports email and IM from AOL, Yahoo! and Windows Live. You can stay logged in to any of these services even when the phone is in standby or you are using another application, so you can always receive new IMs and emails. The Fin also can check your Gmail or Earthlink email account, but this must be done manually, new messages are not automatically received on the phone.
Staying logged in to IM on the Fin drains the battery quickly if your friends message you with any regularity. The same does not seem to be true for the push email from these same providers. The push email is fast and reliable. For example, Yahoo! mail works faster and more consistently than it does on the iPhone.
Just like reading messages, sending messages is done from within that particular service's entry. However there are entries in the main menu for new text / MMS or email messages.
