Hello folks, My iPhone 4s loaded with iOS 7.1.2 is very stable an does everything that I need it to do so I have never felt it necessary to upgrade either the hardware or OS. However, one complaint I have is that VO is not smart enough to filtera out ads when reading web pages in Safari. To see if this situation could be improved I was playing with a couple of ad block apps downloaded from the app store. I'm not sure how I managed to fumble the app installation but whatever I did broke something in iOS such that I no longer had network connectivity , Wifi or cellular. Power cycling and resetting the phone did nothing to help. Also, I could not reset the phone back to factory defaults since I was required to enter my Apple ID which was impossible since I could not connect to the internet. After awhile it seemed my only choice was to put the phone into recovery mode and use iTunes to restore the phone back to factory defaults. This , of course, meant that I was forced to load the dreaded iOS 8.2. This was something I had been avoiding after reading the negative comments that iOS 8 was receiving.anyway, I duly went ahead and eventually got my phone working again with all my apps and music restored.
I have to say that I was very relieved to find the migration to iOs 8 was relatively painless. I have seen several posts that suggest that the 4s becomes very sluggish with iOS 8 installed. Certainly it's no speed demon but for the things that I do it is perfertly usable.
Anyway, now that I have got that out of the way I would welcome recommendations for a trustworthy app that filters/blocks ads in web pages. Thanks in advance.
