pronunciation of 着 in 怎么着 As most of you will probably know, 着 can be pronounced in many ways (depending on the context).

I'm wondering how the 着 in 爱怎么着就怎么着 (meaning: do as you like) should be pronounced. Is it zhe or zhao1, and why? I've heard some people it pronouncing zhe and some zhao1. In MDBG they use zhao1, but say it is also pronounced as zhe, but all the other dictionaries I've checked, I can only find zhe.

EDIT: In the mean-time I've found these websites where people asked for the same question: Baidu, SOSO and Xiaotieba. There doesn't seem to be a consensus, and there are no references.
Dictionaries generally only show the 'standard' heteronymic readings of a Han character, rather than including all its contextual variations. This is the unwritten standard on Wiktionary as well, on which I am an admin. 

As you have precisely discerned, both pronunciations are acceptable in this particular phrase; however, the 'standard' reading of zhe0 would be used in a dictionary for this particular phrase instead as it applies to a wider range of contexts, whereas zhao1 is restricted to this particular context (怎么着).
