My HTC Tattoo loses its mobile broadband connection after a couple of days without a restart. Calling and SMS still work but no data connections. Disabling and reenabling the mobile data connection does not help. Only with a restart the data connection can be used again. Is there a solution to this problem?

I can never end a task easily on the HTC tattoo - is there a shortcut to it I can make, or an easier app to use?

Can the HTC Tattoo act as a wifi hotspot, so that I am able to make my Tattoo an access point and share its internet connection with other wifi enabled devices? If so, how can I do this? I have rooted the phone and I am running a CyanogenMod with Android version 2.2.1. I have already tried the following: 1. Barnacle wifi tether, Android wifi tether - neither of the two worked. 2. I have also seen if there were any default settings to make my phone a wi-fi hotspot, but found there were none of these settings in my phone. 3. I have also tried a new ROM: nFinity Android 2.3.5, but on this ROM also points 1) and 2) stated above were applicable.

I've tried to use HTC Tattoo as a modem on a Windows PC and it worked well, but on a Mac it doesn't work. Some trick or app that i should be aware? My HTC Tattoo uses the default 1.6 ROM with Sense. Thanks.
