Tier 2 - Change of Employer

Hello everyone

Presently I am on a Tier 2 Visa, which I received after bit of a struggle.
I have been working for my current employer since a year now, but my Tier 2 Visa was issued in late August 2013.

Not being satisfied by the current employer, I am looking for a role with another employers and have started applying for jobs.

Considering my last Tier 2 Leave To Remain was granted in August 2013, Can I make a new Tier 2 Leave To Remain application again immediately, or Do I have to wait for 12 months to make another Tier 2 Visa application.

I got this doubt from the below immigration law, and I am confused what it exactly means.

Part 6A - Point based systems - Rule 245HD
(k) The applicant must not have had entry clearance or leave to remain as a Tier 2 Migrant at any time during the 12 months immediately before the date of the application, unless:

(i) the applicant's last grant of leave was as a Tier 2 Migrant,

(ii) the applicant was not in the UK with leave as a Tier 2 Migrant during this period, and provides evidence to show this, or

(iii) the applicant will be paid a gross annual salary (as recorded by the Certificate of Sponsorship Checking Service entry, and including such allowances as are specified as acceptable for this purpose in paragraph 79 of Appendix A) of £152,100 or higher.
