I know how much it sucks to want to use skype on your Wildfire but you can't because the audio sucks, so I made an account to let you guys know this:
In my quest to find a way to call another person for free off my phone like Skype usually is I've tried all the apps I could get for the Wildfire.
Here's how they break down for anyone else stuck with a Wildfire and can't use Skype without choppy audio problems can finally have free calls over data connections and wifi:
1)SIP is not free, so forge any of those apps.
2) Fring - seemed good even though I had to download the .apk manually on my PC and save to SD card then install with an app installer. But after a while it would close itself at random times or the call would be lost. I uninstalled as it always ran in background.
3) Skype Lite - I managed to get an old version of Skype Lite and again used the .apk and app installer to install it on my Wildfire. Skype Lite lets you call your contacts but calls a local number to do this. Thus using your minutes in your price plan and doesn't call over your data connection. I uninstalled.
4) Tango - Available on the android market on Wildfire, wouldn't let me call my friends so never got the test call quality, but might work. I uninstalled.
5) Nimbuzz - AWESOME!! and works! Available throught he Android Market on Wildfire and does more than skype.
You sign in with Nimbuzz but can also sign in with multiple IM accounts such as windows Live messenger, Facebook, Yahoo, Google Talk. ect.
I signed in with my hotmail account and could have great calls to my friend with the same app on iPhone. No lag, doesn't run when you don't want it to, great call quality, easy to use and the test chat "jimmy" is pretty funny too.
Definatley a must have for anyone with a Wildfire.
In conclusion, until Skype are able to tweak the code so it works clearly with the Wildfire, I'm using Nimbuzz as it does everything I need it to, plus more, all for free. It's just a shame I can't use Skype as most of my mates have Skype accounts. I'll leave skype installed so it's notifies me of the updates but there's no point using until then
