If you receive your voicemail as an email attachment (this is fairly common on corporate voicemail systems, less so on mobile contracts.) mVisualVoicemail for Windows Mobile & PocketPC is a useful way of organising your incoming messages.
The app works with Pocket Outlook by harvesting all the incoming voicemail attachments and displaying them in a list with the time of call and contact details of the sender (if known).
You can then scroll through the list, listen to messages and either call back, email or text a reply with one button push (or screen tap).
mVisualVoicemail supports all the common voicemail codecs as well as a few of the more obscure formats that cannot otherwise be played using Windows Media Player.
Available here for $24.95 with a free trial download.
I am forever missing calls and texts due to my phone being at the bottom of a bag or a pocket and my ears being full of MP3s. Remind Me looks like it could save me a considerable amount of grief - perhaps it will do so for you.
The app runs on S60 3rd Edition phones and reminds you (do you see what they did there?) about a missed text message, email or calls by playing an alert every couple of minutes until you deal with it. You can configure both the alert tone and volume as well as the period between reminders.
Reminders are tied in to your phone’s Profile settings so you can elect to receive (e.g.) only call reminders while in ‘General’ or SMS & Email reminders while in ‘Outdoor’ mode.
Remind Me is available from MobiFun on a 10-day trial - the full version costs 10 Euros.
