I have had my bold for one month I set DM up to look for updates and back up my Bold just about everyday (because I am still making little tweaks to contacts and notifiers etc...
I have had possibly 1 update and I say that because it appears to have just re installed 4.6.247 as that is all that is listed all it pulls up are three language
installs none of which I speak or are likely to need to learn soon.
How often does a new OS version come out on DM?
When Bold was new, it shipped with an early release OS. Every subversion upgrade was an improvement over the original.
After a period of time, stable version were accepted for new Sales and upgrades to existing customers.
At this time, with Bold being mature and stable, their is far less benifit to subversions. Some may have specific improvements in some areas, but be less then optimal in others.
Our Storm friends are hoping for the kind of stability Bold has, but in the interm they are blending the best of various subversion into hybrids.
If you choose to test the latest code, keep a roll back copy of your known good OS handy.
