OK...first of all i am new it this...i know a lot of people say this, sorry....and i think i originally posted this in wrong area, so i am reposting. I read a lot on this and the SDX forums to get where I have got right now on my phone, which is: 1. I updated to stock 2.1 using the sprint update tool. 2. I followed the video tutorial to root the phone 3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)). I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...) So that is where I am..but i have a couple of questions. 1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this. 2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone? Sorry for the length of the post..thanks in advance.
