Ok, as I understand this story, the cell phone was taken a way because you didn't want her to be texting in her room at night. However, you trusted her with several other means of night time texting. Despite the fact that she knew you didn't want her night time texting, she went used one of the other methods to night time text. Your husband discovered that she was night time texting and thus punished her by removing all the means of night time texting. To me that seems like a reasonable punishment for a defined period of time -- assuming 2 things: 1. She knew that the reason the cell phone was taken away was because she was not allowed to text at night. (I would probably have a specific time, like no texting after 9PM.) 2. She needs to know why you don't want her texting all night -- she needs her sleep. These rules are not about running her life. They are simply because you all love her, and want what is best for her. She needs to understand this. She needs to hear both of you tell her you love her. Also, this is a trust issue -- you took away the cell phone to make a point, but you trusted her to respect your point by allowing her to keep the other texting devices. Did you violate that trust? She needs to understand that trust is a very delicate thing. Taking away all the devices for a set time, sends a clear message that violating the trust is a BIG issue. She also needs to hear the words. Together you and your husband need to explain to her why this is the right punishment and how long it will last. (You have to back your husband up on this one because it has already happened. Showing your daughter a divided front between the two of you is only going to result in more problems later.)
So on the first one I am kind of on the side of your husband but I would set a specific time that the devices need to be downstairs; and I would also list what devices. I would back up my husband's punishment for an agreed upon time period, and I would let him be the one to tell her when she'll get them back.
I think the 10PM bed time on a school night is reasonable.
Regarding the seeing friends during the week. That seems like a bigger issue that you all might need to work out. She does need a social life; however, she also needs limits, and you need to know where she is. Does she have any responsible girl friends that she could have over once or twice a week to help her watch her brother?
We always had a rule when I was growing up, and I have it with my children. The parents need to know where you are going and when you'll be back. If you will not be home on time, you must call before the time you were due to arrive. It was also explained to me when I was a kid, and I have explained it to my children this way -- this rule is not to control you, it is because we love you and care about you, and when we don't know where you are we worry. Calling or being on time, is about being consider of other people's feelings and being respectful. Given all this, I would have a HUGE problem if my daughter went for a run to a friends house and I had to call her to find out where she was. She should have called me. She wouldn't be going running alone for a couple of weeks.
It also sounds to me that your husband is scared that something is going to happen to your daughter. He may be being "overprotective" but this is probably because of fear. I know my husband and I have the biggest fights when we are worried about our children. We aren't really mad at each other we just get really emotionally keyed up and yell when anything bad happens to our kids.
Remember most guys aren't worried what the girls are going to do, they are worried what the guys are going to do. Remember they were once teenageboys, we weren't. They may have a point that we haven't really considered.
It sounds to me like your husband cares about your daughter very much, and that you and your daughter are very luck to have someone in your life that cares this much. Now you just have to work on communicating better, which isn't easy.
Good Luck!
