So I finally got around to downloading and installing Yahoo! Go mobile. Am I impressed? Yes and no… It was not that straightforward to download the application and get it running on a Nokia N70. There are some aspects that are quite unintuitive. Overall, I think it’s a good start. I mean essentially it is an application that launches a few other mini-applications (for photos and Yahoo! Messenger), some built-in S60 applications like Mail and Calendar and then has a bunch of Web-links for content (like “ringtones” — ugh!). One problem is: I can’t get it to bring up Opera as the default browser when it initiates a browsing session (admittedly this is probably a S60 problem but it would be nice for the Yahoo! application to give me the option of setting an alternate browser). I wish the content wasn’t just a link off to a browsing session — how about reading news through a built-in RSS reader? To be fair, they’ve indicated that mobile Konfabulator-style widgets are the next step, so maybe integration of these will solve some of these issues. The background synchronization and email config seems to work fine — I was up and running with my Yahoo! mail account in minutes once the application installed. I wish you could replace the phone’s “active idle” screen with the Yahoo! Go application and that the applications’ main screen could contain more dynamic content (like a mini-my-yahoo: number of messages in your inbox, top headlines, etc…). Verdict: It’s a great start.
