It seems like the gold rush of applications for the T-Mobile G1 (see my review) has slowed down considerably over the last couple of weeks with just a few apps trickling out here and there. I imagine most of this is because developers are waiting for the commercial functionality when they can sell applications in the Android Market. However, two applications I just found this morning when I turned on my G1 were Opera Mini 4.2 beta and Fusion Voicemail Plus and think these are both worthy applications you should try out on your G1.
Opera Mini 4.2 beta gives you an alternate web browser for very fast internet access (due to the Opera server doing much of the work). One reason I love Opera Mini on all my mobile devices is the ability to login to synchronize Opera and have all my bookmarks appear on every device in a consistent manner. Granted, the included browser on the G1 is very good, but it is nice to have alternatives available too.
Fusion Voicemail Plus brings visual voicemail to the G1! You do need to first sign up for a free account online (you can do it from your G1 browser) before using the application on your G1. Fusion Voicemail is a free service that lists your voicemail messages on your G1 screen and lets you play them when you want. You can also forward other voicemail systems (home, work, other mobile phones) to your G1 number and get those voicemails into a visual voicemail system too.
You can check out the video of the system working on the T-Mobile G1 below.
I also see that this application is available for Windows Mobile 5 and 6 devices so I will have to try it out on my HTC Fuze as well.
